What is the function of the wire diameter compensation function of the digital tension tester?

So some digital tension testers on the market have a wire diameter compensation function, and some digital tension testers do not have wire diameter compensation function. What is the difference?

the digital tension tester is a mechanical measurement tool used to measure the tension of the wire. It mainly uses the principle of three guide wheels to realize the tension measurement. The material to be tested passes between the three measuring guide wheels, and the trigonometric function algorithm is used to get the tension on the line. the enveloping angle formed when the wire passes through the three guide wheels is the key factor for calculating the final tension value. Therefore, when wires of different wire diameters pass through three guide wheels, due to the different thicknesses of the wires, the angles formed will inevitably be different, which will affect the final tension value calculation. Therefore, when designing a digital tension tester, compensation must be made. There are relatively few brands with wire diameter compensation on the market. For example, the universal tension meter NT series digital tension tester provided by Shenyang Betten Technology Co., Ltd. is a digital display tension tester with wire diameter compensation and automatic zero-clearing functions. Models are NT-1000, NT-2000, NT-5000, etc., suitable for measuring the tension of copper wire, yarn, enameled wire, steel wire and other materials.

The NT series has 10 kinds of tension ranging from 1.0-200.0cN to 10.0-100.0daN. The width of the measuring head varies with different ranges.

Features:

1. The patented technology automatically resets the meter to zero , which improves the measurement accuracy and facilitates measurement.

2. Equipped with a wire diameter compensator, which compensates errors caused by different wire diameters and improves measurement accuracy

3． Equipped with lead frame and guide wheel movement structure, it is easy to capture the tested material.

4． V-groove aluminum measuring guide roller with ball bearing.

5. Rugged, non-slip aluminum case, resistant to electrical interference.

6. LIPO lithium-ion polymer battery (about 13 hours of continuous operation).

7. The tested material, the guide roller, and the screen are located on the same plane. During the test, the test data, the status of the guide roller and the tested material can be seen.

8. A maximum of 10 materials can be accurately calibrated. With the wire diameter compensator, the tested wire diameter range is larger.

9. character menu setting interface, easy to operate.

10． According to different ranges and needs, the measurement value display unit can be selected g, kg, c N, N, daN, lb

11. It can record the maximum value, minimum value, peak value and average value in the measurement process, and can also store 10 independent measurement values.

12. Programmable setting of the maximum and minimum value of the trend status bar, clearly determine the range of tension change, and have the advantages of mechanical instrument trend display.

13. Provides fine adjustment of display results. If There is a slight deviation between the material measured on site and the standard calibration material, and accurate values can be displayed without recalibration.

14. Function settings can be protected by passwords to improve setting security.

15. Betten tensiometer provides two display modes, taking into account the advantages of accurate electronic tensiometer reading and mechanical tensiometer trend display.
